Influence of different agricultural management practices on soil microbiome
No full textMicrobiomes are the collection of all microbial inhabitants of a given system. At the level of the soil, the microbiome includes four major groups of microorganisms: bacteria, fungi, archaea, and protozoa, as they are the main organisms for essential soil processes such as nutrient cycling, decomposition of organic matter, and plant growth promotion. A healthy soil microbiome is essential for sustainable agriculture and the overall health of terrestrial ecosystems. Some agricultural management practices, i.e. irrigation, can have a significant impact on the soil microbiome. The quality and quantity of irrigation water can affect the abundance and diversity of microorganisms in the soil. For example, excess irrigation can lead to waterlogging, which can create anaerobic conditions that favour the growth of certain types of bacteria. On the other hand, irrigation water in the right amounts can have a positive impact on the soil microbiome and promote plant growth. To test this hypothesis in the agricultural year 2022, a research was carried out on maize and soybean grown under irrigated conditions, to analyse the variations of microbial density during the vegetation period
Selected Characteristics of Multifloral Honeys from North-Eastern Romania
No full textThe aim of this research was to evaluate some characteristics (moisture, total solid substances, specific gravity, pH, FA, ash, electrical conductivity, TPC and TFC, potassium, calcium, magnesium, sodium, phosphorus, zinc, copper, manganese, nickel, cobalt, and lead) of fifteen multifloral honey samples. The quality of the investigated honey was confirmed by the obtained results: moisture, FA, and EC values were below the limit value regulated by the legislation. The average content of total polyphenols and total flavonoids of 29.91 mg GAE/100 g and 2.13 mg QE/100 g confirm the antioxidant properties of honey. Determination of minerals showed that potassium (101.4–1212.6 mg kg−1) was the most abundant mineral in honey, followed by sodium (40.7–302.3 mg kg−1) and calcium (41.8–230.9 mg kg−1). Lead was found in two samples, with a content under the limit stipulation by legislation; nickel was found in one sample of 0.10 mg kg−1, and the content of cobalt was below the detection limit. Significant correlations (p < 0.001) were observed between mm Pfund and electrical conductivity, TPC, TFC, P, Ca, and Zn; strong correlations (p < 0.001) were between electrical conductivity with Ash, TPC, TFC, K, and P. FTIR analysis confirmed the differences obtained by analyzing multifloral honey samples

Traditionally recognized for its contributions to the agri-food industry and biofuel production, rapeseed's value extends beyond its seeds to its often-overlooked stalks. In recent years, research efforts have intensified to explore the chemical valorization of rapeseed stalks, recognizing their untapped potential as an abundant and valuable biomass resource. By overcoming technical challenges and optimizing valorization pathways, researchers can unlock the full potential of rapeseed stalks, contributing to the transition towards a bio-based economy and addressing environmental and economic challenges in agriculture and chemical industry
Cercetări privind utilizarea pereților verzi în instituții medicale
Get PDFThe main purpose of the current paper is to highlight the impact of the design of a green wall in a medical recovery clinic where patients with various deficiencies are treated, which may or may not involve comorbidities. Due to the hospital environment, they chose to use lichens and stabilized plants, which don’t require additional costs or specialists for maintenance. Also, there aren’t risks related to the emergence of complications related to the patients’ health, and the colours of the plants are maintained for a long time and don’t require extensive spaces. A connection with nature has been found to reduce stress and remedy mental fatigue. This is due to our body’s automatic reaction to seeing and being around natural elements. The methodology of interior and exterior revitalization of a hospital is based on the knowledge of the principles of healing and the design of therapeutic gardens and their positive influence on the psyche, perception and health of human beings. This methodology concerns the connection between humans and nature, the influence of nature on a person’s psychological perceptions, the connection between nature and human health, and last but not least, the importance of green vegetation as a supplement to a treatment
Caracteristici și tendinte ale sistemului cooperatist din agricultura Uniunii Europene
Get PDFThe development of the cooperative system in the agriculture of the EU countries was achieved by permanent adaptation to the socio-economic conditions specific to the territory in which it was born. As a result, community agricultural cooperatives have many common characteristics but also particularities. The changes in the agricultural and agri-food sectors have led cooperatives to focus on adopting strategies that can keep them competitive: introducing high quality standards, branding own products, emphasizing the process of vertical integration, multiplying processing operations, accepting as members farmers from outside the host countries and even abandoning the legal status of a cooperative
Utilizarea analizei spectrale pentru dovedirea structurii heterociclice a unui derivat de piridazină
Get PDFBy [3+2] cycloaddition reaction, between pyridazine and an alkene in alkaline medium (Et3N), were obtained in situ a pyrrolopyridazine adduct.
The structure of the compound was proved by spectral analysis, using the following spectral methods: IR, 1H NMR, 13C NMR and MS. Taking into account the chemical shifts, the coupling constants and signal splitting in the spectra, the only reasonable structure for the cycloadduct is that one presented
Effects of antioxidant treatment on cell differentiation in rabbit embryos
Get PDFThe antioxidant coenzyme Q10 can influence the expression of genes involved in apoptosis and energy metabolism of
oocytes and quercetin can improve oocyte maturation and early embryonic development. In this study, the gene
expression of GATA6 and NANOG in rabbit embryos was assessed using the qRT-PCR reaction. The groups were:
group A- control group (no treatment added), group B (hormonal treatment of superovulation, which included the
administration of PMSG and hCG), group C (administration of quercitin) and group D (administration of Coenzyme
Q10). Our results show that the expression of the two genes was different depending on both the stage of embryonic
development and the treatment administered. The highest values of gene expression for GATA6 and NANOG were
obtained in groups 2, 4, 7, 8 and 9, corresponding to morula and blastocyst stages. In addition to the fact that NANOG
and GATA6 are factors that are involved in early embryonic development, we believe that the administration of
extrapituitary gonadotropins and antioxidants contributed to the increase in gene expression
Nitrogen feeding of winter peas at the spring vegetation recovery stage
No full textIn a field experiment from
2020–2023 on the southern chernozems of
the Odessa region of Ukraine, we studied the
effect of the doses and timing of mineral
nitrogen application when growing winter
peas on the tuberization process and crop
productivity. Mineral nitrogen in doses of
30, 45 and 60 kg/ha in the form of
ammonium nitrate was applied in different
development phases of winter peas under
seedbed cultivation: foliar top dressing with
urea solutions during the resumption of
spring vegetation, the budding phase and the
beginning of grain filling. Winter pea of the
Enduro variety was sown annually on
October 20, with a row spacing of 15 cm and
a rate of 1.2 million germinating seeds per
hectare. The previous crop was winter
wheat. The conditions of the Southern
Steppe of Ukraine for winter sown peas were
shown for the first time. The introduction of
mineral nitrogen at a rate of 30–60 kg/ha
into the soil during sowing inhibited the
formation of nodules from the active spring
growth phase. The mass of nodules on the
roots of pea plants decreased by 30–50%
compared to the control variant without
nitrogen application. The same norms of
mineral nitrogen introduced in early spring
during the resumption of vegetation on the
leaf in the form of aqueous solutions did not
have a negative impact on tuberization. The
correlation coefficient between the dose of
mineral nitrogen and the number and weight
of nodules did not exceed 0.37, indicating a
weak relationship between these indicators.
The share of influence of mineral nitrogen
norms did not exceed 13.7%. With this
method of application, the nitrogen content
in the vegetative mass of winter peas
exceeded the control variant by 18–27%
On a special symmetry in the dynamics of complex systems in a holographic-type perspective
No full textBy operating with the Scale Relativity Theory in the dynamics of complex systems, we can achieve a description of these complex systems through a holographic-type perspective. Then, gauge invariances of a Riccati-type become functional in complex system dynamics, which implies several consequences: conservation laws (in particular, for classical dynamics, the kinetic momentum conservation law), simultaneity and synchronization between the structural units (of a complex system) dynamics, and temporal patterns through harmonic mappings
A case of bilateral cryptorchidism, ultrasound diagnosis and surgical therapy in tomcat
Get PDFBilateral cryptorchidism is seldom in tomcats. Clinical diagnosis is challenging because the testicles can be located in
the abdominal cavity, a situation in which they cannot be palpated, or in the inguinal region, a situation in which they
are difficult to identify due to the subcutaneous fat layer.
Ultrasound is the most available imaging method for diagnosing this pathology. The testicles have a characteristic
structure that is easy to recognize. Ultrasound localization of the testicles allows the approach through a smaller
incision, and the use of a castration hook to extract the testicle from the abdominal cavity.
The blood vessels and ductus deferens can be ligated with absorbable suture material, but can also be sealed with
bipolar forceps. The reason why vascular sealing with bipolar forceps was chosen was to reduce surgical time and to
reduce the amount of embedded foreign material. From a histopathological point of view, coagulation necrosis was
observed on both blood vessels and ductus deferens.
The suture of the abdominal wall was made in a continuous pattern. Skin staples were used to save time
